Romans 15:20-note And thus I aspired to preach the gospel, not where Christ was already named, so that I would not build on another man's foundation; 1 Corinthians 3:10 According to the grace of God which was given to me, like a wise master builder I laid a foundation, and another is building on it. But each man must be careful how he builds on it. 11 For no man can lay a foundation other than the one which is laid, which is Jesus Christ. 12 Now if any man builds on the foundation with gold, silver, precious stones, wood, hay, straw, Ephesians 2:20 having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, 1 Timothy 6:19 storing up for themselves the treasure of a good foundation for the future, so that they may take hold of that which is life indeed. 2 Timothy 2:19-note Nevertheless, the firm foundation of God stands, having this seal, "The Lord knows those who are His," and, "Everyone who names the name of the Lord is to abstain from wickedness."

He does not mean the OT prophets for they knew nothing of the NT Church, the building that Paul is describing in this passage. Note carefully that although apostles and prophets are "foundational", they are not the ultimate foundation, which is Christ Himself. John MacArthur explains foundation of the apostles and prophets writing that... Because the Greek genitive case appears to be used in the subjective sense, signifying the originating agency, the meaning is not that the apostles and prophets were themselves the foundation—though in a certain sense they were—but that they laid the foundation. Paul spoke of himself as “a wise master builder” who “laid a foundation” and went on to say, “For no man can lay a foundation other than the one which is laid, which is Jesus Christ” (1Cor. 3:10, 11; cf. Ro 15:20-note). (MacArthur, J: Ephesians. Chicago: Moody Press)
